Naa... but proxy_auth ACL's could be made to refer to auth groups, not
only user names. Mostly needs a syntax definition, and support in the
helper protocol.

Want to be able to make lists of groups (unions, not intersections as
done by http_access).

Yes, and both are required I think.

'a' is tied to the authentication helper.

'b' is a separate helper, not really groups but can be used to implement
groups. Not at all tied to authentication (except that authentication ID
can be one of the selection criterias)

Hoever, proxy_auth IS the group definition, not the ACL telling which
groups to match.

Lets say your authentication system has 20 different groups, all
published by the auth helper to Squid.

You want to give 5 of these groups access to a given resource, deny 6
from some other resource, and allow 2 to proxy to anything else.
